The Star-Delta Calculator is a free Android-based program developed by Peter Ho that allows users to calculate the conversion between star and delta networks. It is a convenient tool for engineers and technicians who need to convert between these two types of networks in their work.

One of the main features of this calculator is its ability to convert resistor star networks to delta networks and vice versa, which can save users a significant amount of time. In addition to these basic features, the Pro version of the calculator includes the ability to convert capacitor and inductor star networks to delta networks and vice versa, as well as the conversion of impedance networks.

It is important to note that for those who need support, the designated email should be used rather than the feedback area. This ensures that any questions or concerns are addressed promptly and efficiently.

Overall, the Star-Delta Calculator is a useful and convenient tool for engineers and technicians who regularly work with star and delta networks.
